I don't see how you could possibly read it as a dig against the site. The whole thrust of the argument was, don't use any documentation as absolute for your site, except that which was installed along with the version of perl that you have.

"Updating" the documentation on the site even to 5.6 does not solve that problem since even then it still only applies to the people who have 5.6 installed.
